Abstract

PURPOSE:To improve labor saving and safety of an inspecting person in a man conveyer provided with a moving footboard by providing a portable type operation board for remote-controlling the traveling speed of the footboard at the time of inspection. CONSTITUTION:A switch box 7 for inspecting operation which serves as an operation board is connected to a controller 5 through a cable 6 provided with a receptacle. In the switch box 7, a start switch 8, a forward switch 9 and a backward switch 10 of push-button type and a change-over switch 11 of dial type are disposed. When the start switch 8 is pressed, inspecting operation is available, and when it is released, the operation is stopped. At the time of inspection, an inspecting person turns the change-over switch 11 to set it to any memory of 'low', 'medium' and 'high'. For turning on the start switch 8 and advancing the footboard 3, the forward switch 9 is turned on, and for retracting it, the backward switch 10 is turned on. It is thus possible to move the footboard 3 at a desired speed and in a desired direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a passenger conveyor that is applied, for example, as a moving walkway.

(Prior Art) A moving walkway is equipped with a movable footboard, and the footboard is moved by an electric motor at a speed of, for example, 30 mm/min. This moving walkway is regularly inspected for safety reasons.

In this case, by turning on and off the start switch and stop switch on the control panel for normal operation, you can turn on and off the motor and move the treadle intermittently, or move the treadle back and forth. I try to work by letting them do things.

However, with this method, the movement speed of the treadle is fast, and there are problems in that the treadle cannot be accurately stopped at the desired position to be inspected, and that sufficient inspection cannot be performed.

In order to solve this problem, it has been devised to attach a handle to the shaft of the electric motor and manually rotate the handle to move the treadle at low speed for inspection.

(Problem to be solved by the invention) However, in this case, although it is possible to move the tread according to the inspection details, the moving distance of the moving walkway is longer than that of an escalator, so it is difficult to turn the handle by hand. It is a very heavy task and requires a lot of human effort.

Additionally, if the location to be inspected is far from the location where the motor is installed, the system communicates in a loud voice, but in many places it is difficult to hear in areas with high external noise, which also poses safety issues.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a passenger conveyor that allows the inspector to move the treadle as he or she wishes during inspection.

[Structure of the Invention] (Means for Solving the Problem) In order to solve the above-mentioned problems, the present invention provides a portable operation for remotely controlling the moving speed of the step board during inspection in a passenger conveyor equipped with a moving step board. It is equipped with a board.

(Function) By making the control panel that remotely controls the moving speed of the treadle portable during inspections, there is no need for a person to operate the electric motor, and the inspector can move the treadle himself for inspection.

(Example) The present invention will be described below with reference to an example shown in the drawings.

Figure 2 shows a moving walkway, with balustrades 1 and 1 placed facing each other at a distance from each other, and movable handrails 2 running along the periphery of these balustrades 1 and 1, respectively. There is. Moreover, a step board 3 is movably provided on the bottom of the moving walkway.

Furthermore, a machine room 4 is provided in the front part of the moving walkway, and inside this machine room 4 there is an electric motor (not shown) for moving the step stool 3 and a control device for controlling the operation of this electric motor. 5 is provided.

Incidentally, a switch box 7 for inspection operation as an operation panel is connected to the control device 5 via a cable 6 with an outlet. As shown in FIG. 1, this switch box 7 includes a push-button start switch 8 and a forward switch 9.
, a reverse switch 1°, and a dial type changeover switch 11 are provided. When the start switch 8 is pressed, inspection operation is possible, and when it is released, the operation is stopped.

The changeover switch 11 is adapted to change the moving speed of the footboard 3 during inspection into three stages: low speed a, medium speed b1, and high speed C, as shown in FIG. d is the moving speed of the footboard 3 during normal operation, which is usually 30 mm/min.

Note that this switching between low speed a, medium speed b, and high speed C is a known technique that can be easily achieved by controlling the induction motor with an inverter.

Therefore, during inspection, the inspector holds the switch box 7 in his hand and first rotates the changeover switch 11 to set it to the desired low, medium, or high memory.

Next, the starting switch 8 is turned on, and if the footboard 3 is to be moved forward, the forward switch 9 is turned on, and if the footboard 3 is to be moved backward, the reverse switch 10 is turned on. Thereby, the footboard 3 is moved in a desired direction at a desired speed.

Note that the present invention is not limited to the above-mentioned embodiment, and the cable 6 of the switch box for inspection operation may be omitted and the operation may be performed using radio waves in the same manner as a television remote control.

In addition, electrical outlets are installed at several points along the entire length of the moving walkway.
By connecting the switch box 7 to this outlet, the length of the cable may be saved.

[Effects of the Invention] As explained above, according to the present invention, the inspector can control the speed of the treadle himself during inspection, which has the effect of saving the inspector's labor and improving safety. .

[Brief explanation of drawings]

The drawings show one embodiment of the present invention; Fig. 1 is a perspective view showing a switch box, Fig. 2 is a perspective view showing a moving walkway, and Fig. 3 is a graph showing changes in the speed of the treadle during inspection. It is. 3...Treadboard, 7...Switch box (operation panel for inspection).
